Re: powder for long barreled 338 lm
RL25 will get you that velocity. Do a 338LM search in the reloading forum.

+1 I use RL25 thru a 30" tube for 250's

Re: powder for long barreled 338 lm
I shot Retumbo for a good while and still do but I also use reloader 19, seems that I must be the only one but with 250 gr. smk's or scenars I hit 2950 with ease.

Go with Retumbo the long barrel and the extreme powder will get you great velocity with less pressures and small extreme spred it is more stable at diferent tempritures.

Re: powder for long barreled 338 lm
i have heard n-165 and n-170 has worked in the 338 lapua. how is it in a long barrel and with extreme changes in temp.? boretech bullets gives 90.0 gr of retumbo and 80.0 gr of n-165 for their loads with the bullet 70 thousandths off the lands

Re: powder for long barreled 338 lm
The VV 100 series powders are nearly as good as the extreeme powders made here in Australia By ADI for Hodgdon so VV170 would also be a good choice and is good in extreme changes in weather you could give it a try if you wanted to but the cost diference between it and retumbo gets my first try with Retumbo you will be GTG.

H1000
RL25
Retumbo
All good powders. My rifle has a 26" barrel.
N165 , IMHO, isn't a good powder. Too much recoil, and that's with a brake.
